H 0. H 12d. H E-29 Integration Calculations • The following four inputs are required for integration calculations: a function with the variable x; a and b, which define the integration range of the definite integral; and n, which is the number of partitions (equivalent to N=2n) for integration using Simpson’s rule. d expression P a P b P n T •Use the COMP mode for integration calculations. 5 • Example: To calculate: .1 (2x2 + 3x + 8) dx d 2 p x K+ 3 p x + 8 P 1 P 5 P 6 T 0. = 150.6666667 Note! •You can specify an integer in the range of 1 to 9 as the number of partitions, or you can skip input of the number of partitions entirely, of you want. •Internal integration calculations may take considerable time to complete. •Display contents are cleared while an integration calculation is being performed internally. Degrees, Minutes, Seconds Calculations •You can perform sexagesimal calculations using degrees (hours), minutes, and seconds, and convert between sexagesimal and decimal values. • Example 1: To convert the decimal value 2.258 to a sexagesimal value 2.258 = A O • Example 2: To perform the following calculation: 12°34’56” 3.45 12 I 34 I 56 I-3.45 = 2.258 2°15°28.8 0. 43°24°31.2 E-30 Technical Information k When you have a problem...... If calculation results are not what you expect or if an error occurs, perform the following steps. 1. F1 (COMP mode) 2. FFF1 (DEG mode) 3. FFFF31 (NORM 1 mode) 4. Check the formula you are working with to confirm it is correct. 5. Enter the correct modes to perform the calculation and try again. If the above steps do not correct your problem, press the P button (see page 35 or 36) on the back of the calculator to reset it. Pressing the P button deletes all data stored in calculator memory. Make sure you always keep written copies of all important data. If the above steps do not correct the problem, press the 5 key.The calculator performs a self-check operation and deletes all data stored in memory if any abnormality is detected. Make sure you always keep written copies of all important data. k Error Messages The calculator is locked up while an error message is on the display. Press t to clear the error, or press e or r to display the calculation and correct the problem. See “Error Locator” on page 10 for details. Ma ERROR •Cause •Calculation result is outside the allowable calculation range. •Attempt to perform a function calculation using a value that exceeds the allowable input range. E-31 •Attempt to perform an illogical operation (division by zero, etc.). •Action •Check your input values and make sure they are all within the allowable ...
